Question About Retail

Does it seem to you that many stores from national retailers to your neighborhood grocery are making more billing errors than ever, and that the mistakes (in our super-technology age) are usually to their benefit? My readers know I am no raving anti-corporate leftist, but it seems ridiculous that certain retail stores can not deal with a coupon downloaded and printed from their websites or that three out of the last five times we have shopped at our nearby grocer, they have overcharged us (and once, one of their managers was rude and confrontational in correcting their mistake). These are trying times and some of those who work in retail seem well past the point of caring about their customers.
